Application led December 30, 1929. `Serial NdA-17,444.

My invention relates to improvements in mailing folders and envelopes and methods ofmaking same. f Y' One of the objects of my invention is'to provide a novel mailing folder and envelope which simulates the usual -envelope with'- its individual letter contents; which is'simple, cheap, and easily and quickly formed from a blank to envelope form.

Affurther object of my invention is the provision o f a novel blank from whichY the envelope and folder may be formed'.

A still further object of my invention is the provision of a novel method of making my improved folder and envelope.

Still another object of my `invention is the vprovision of ay novel folder and envelope, which, when formedfrom the blank into envelope form, will withstand rough handling in the mails without being sealed' and Without liability of being accidentally opened, and which, when opened in the manner usual in the opening of envelopes, will present the appearance of an ordinaryletterhead.l

y The novel features of my invention are hereinafter fully described and, claimed.

Similar reference characters designate similar parts in the different views.

IlnVJFig.v 1 is shown a blank of suitable material, such as paper, adapted'for receiving printing or writing. The blank has a rectangular body having avmiddle portion 1 and twoend portions 2 and 3 separated from the middle portion 1 by two transverse creases 4 and 5 which extend across a flap 6 at one longitudinal edge 4of the middle portion 1..

'The flap `6 at its ends isv provided" with two tabs 7' andSl respectively, which 'extend from the creases 4 and 5 and are vnarrowly spaced respectiyelyby slots 9 and 10 from the adjacent longitudinal edge of the body.

" The body is provided, preferablymidway between its longitudinal edges with a longitudinal crease-11" extending-from end to end `of the body.' p g In the form of blank. shown in-k Fig. 1,-the -ii'ap- 6 is provided with two longitudinal creases 12 and 13 Which respectively aline `with therinner edges of the-tabs 7 and 8 and fthe adjacent longitudinal'edge of the'bocly.

Printed matter simulating 3 letterheads with4 individual letter composition matter may beinscribed on eitheror both sides of thehody;A

i@ lgtisaplan vewofaelettedalleetfrora' -ileliarmnetlla@hieraeflevsl??? fiom the blank shown in Fig. 1, the tabs 7 and 8 are folded over one side of the flap 6 along the creases 4 and '5. The tabs, as shown, are of suicient length as to overlap each other when so folded. After the tabs 7 and 8 are folded, the flap 6 is folded at right angles along the crease 12 with the tabs 7 and 8 at the side next to the middle portion 1 of the body, as shown in Figs. 2 and 3.

The end portions 2 and 3 of the body are then folded along the creases 4 and 5 one over the other and over the side of the middle portion 1 from which extends the flap 6, Figs. 2 and 3. Y

The folded over end portions 2 and 3 and the middle portion 1 are then doubled by folding along the crease 11 toward the tabs 7 and 8 and flap 6.

The flap 6 is then folded along the crease 13 over the end portions 2 and 3 and the middle'portion 1, and the adjacent free edge portionsV of folded end and middle portions of the body are inserted into the pocket 14 formed by the flap 6 and the tabs 7 and 8, as shown in Figs. 4 and 5. The inserted end and middle portions and flap 6 are then pressed tlatwise, as in Fig. 6.

This completes the formation of the folderandenvelope, which may have the superscription inscribed on the side opposite to hat rat which is disposed the flap 6, as in If desired the portion of the tab 7 which overlaps the tab 8 may have a mucilaginous coating 15 yapplied thereto for fastening together the tabs, but this is not essential and may be dispensed with, as the tabs will remain folded after the iap is folded to form the pocket 14 and the folded portions 2, 3 and 1 are inserted into the pocket.

By having the Hap 6 folded at right angles along the two creases 12 andy 13, it has no tendency to spring open, so as to permit the inserted portions withdrawing from the pocket. A

Referring to Fig. 8, 16 designates a sheet having adjacent to one longitudinal edge alined perforations at opposite sides respec.

tively of the middle of the sheet, such as two alined longitudinal slots 17 and 18, correspondingto the slots 9 and 10 of Fig. 1.

This slotted sheet may have the printing and writing inscribed thereon, while the sheet is in the condition shown in Fig. 8.-

The sheet 16 may then have its end edge portions cut to intersect the slots 17 and 18. This may be effected by transversely shearing off the end portions along the kdotted lines 19 and 20, Fig. 8, which lines cross transversely the slots 17 and 18 respectively adjacent to the outer ends thereof. Such severing Yof the end portions of the sheet 16 produces a blank having a rectangular body provided with two end portions 21 and 22 and a middle portion 23, respectively corresponding to the portions 2, 3 and 1 of Fig. 1. The portion 23 is provided at one longitudinal edge with a Hap 24 having end tabs 25 and 26, corresponding to the flap 6 and its tabs 7 and 8.

The body is provided with two transverse creases 27 and 28 which extend across the tabs 25 and 26. The body is also provided with a longitudinal middle crease 29 corresponding to the crease 11 of Fig. 1.

The flap 24 is provided with a longitudinal crease 30 extending from the slot 17 to the slot 18.

The blank, thus formed may be folded, to form a folder and envelope, in a manner similar `to that described with reference to the folding of the blank shown in Fig. 1.

The tabs 25 and 26 are folded respectively over the flap 24 along the creases 27 and 28, Fig. 9. The end portions 22 and 21 are then one over the other over the middle portion 23 at the side at which are disposed the tabs 25 and 26, Figs. 10 and 11.

The flap 24 is then folded along the crease 30, so as to form a pocket 31, corresponding to the pocket 14. a

The end portions 21 and 22 and the middle portion 23 are then folded along the crease 29, and the free adjacent ends of these folded portions are inserted into the pocket 31, as shown in Fig. 12. This completes the formation of the folder and envelope from the blank formed from the sheet 16 of Fig. 8.

By inserting a. knife 32 between the flap 24 and the body portions, as shown in Fig. 13, the flap 24 may be severed from the body along the crease 30, thus leaving the body in the rectangular form simulating 3 letterheads as shownin Fig. 14.

. Inv like manner the Hap 6 may be severed from the body in the form shown in Fig. 6, thus removing the flap 6 and the tabs 7 and 8 from the body so as to leave a substantially rectangular sheet simulating 3 letterheads.

The sheets corresponding to the sheet 16 having the slots 17 and 18, and with the end portions uncut, as shown in Fig. 1, may be printed and handled without liability of deformationy by the tearing off of the tabs 25 and 26. After printing or being typewritten,

the sheets 16 may be sheared off at the ends along transverse lines intersecting the outer ends of the slots 17v and 18, as along the lines 19 and 20, Fig. 8. A large number of the sheets may be sheared at a time, thus elimivnating individual handling.

I do not limit my invention to the structures shown anddescribed, as various modiications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

Vhat I claim is 1. The method of makinga blank for a mailing folder and envelope consisting in providing in a rectangular sheet two longi-V tudinal alined slots, at opposite sides respectively of the middle portion of the sheet, and cutting opposite edge portions of the sheet to intersect said slots adjacent to the outer ends thereof, thereby forming a rectangular body having at one edge between said slots a flap having, at opposite ends respectively, two tabs.

2. The method of making a blank for a mailing folder and envelope consisting in providing in a rectangular sheet two alined longitudinal slots, at opposite sides respectively of the middle portion of the sheet, and transversely severing opposite edge portions of the sheet across said slots respectively adjacent to the outer ends thereof, therebyforming a rectangular body having at one edge between said slots a flap having, at opposite ends respectively, two tabs.

3. rlhe method of making a mailing folder and envelope, consisting in providing in a rectangular sheet two longitudinal alined slots, at opposite sides respectively of the middle portion of the sheet, cutting opposite edge portions of the sheet to intersect said slots adjacent to the outer ends thereof, thereby forming a rectangular body having at one edge between said slots a iiap having, at opposite'ends respectively, two tabs, folding said tabs over the same side of the flap and folding said flap over said body to form a pocket, folding opposite portions of the body over the middle portion thereof at the side at which are located said tabs, and folding the said folded opposite portions and the middle portion of the body toward and inserting them into said pocket.

4. The method of making a mailing folder and envelope, consisting in providing in a rectangular sheet twolongitudinal alined slots, at opposite sides respectively of the middle portion'of the sheet, transversely severing opposite `edge portions ofthe sheet across said slots respectively adjacent to the outer ends thereof, thereby forming a rectangular body having at one edge between said slots a flap having, at opposite ends respectively, two tabs, folding said tabs over the same side of said flap and folding said flap over the body to form a pocket, folding opposite portions of said body over the iniddle'portion thereof at the side at which are located said tabs, and folding the said folded opposite portions and the middle portion of the body toward and inserting them into said pocket. i

5. The method of making a. mailing folder and envelope consisting in providing in the side portions respectively, and at opposite sides respectively of the middle portion of a rectangular foldable sheety adjacent to one edge thereof, alined perforations, ysevering,

said side portions in alinement with said perforations, thereby forming at said edge of said sheet a Hap having two tabs at its ends respectively, folding saidk side portions over said middle portion, doubling said folded portions toward said flap, and folding said tabs inwardly and disposing them between said doubled portions.

6. A mailing folder and envelope comprising a foldable sheet having a rectangular body having at one edge of its middle portion a ,flap having two tabs at its ends respectively, the side portions of said body being folded over said middle portion and said folded portions being doubled toward said Hap, and said tabs being folded inwardly and disposed between said doubled portions.

ln testimony whereof I have signed my name to this specification.
